nited States, residing'at Leominster, co nty of Worcester, Commonwealth of tain new and useful Improvementsin Tree Insulators, of which the following is a specification.

This invention relatesV to tree insulators adapted to deflect the current-carrying cables of electrical distribution systems past trees, posts, or` otlier objects intervening in the direct line of the cables. Y

Ordinarily such insulators as have `beendevised for this purpose fasten to the tree itself, and 'in this'respect are objectionable.

To the end therefore of providinga tree insulator which will avoid have devised myl present invention.

According to my invention, the tension .of

the taut' current-carrying cable itself is utilized to eifectively position the insulator relative tothe intervening tree so that the cable is deflected past the tree, thus obviating the necessity of directly fastening the insulator to the tree.

lv y'insulatory isv simple and inexpensive in construction, and-not -only effectively insulatcs the current-carrying cable from the tree or other intervening object, but prevents wear or chaing of the insulating cover ,of the cable, which chaing exposes the current wires to the tree, thereby causing the tree to become burned and a short circuit to vbe established in the distributing system.

These and certain .other features of ad-v vantage which will appear more particularly hereinafter are secured in the device of the present invention, lthe construction and manner of use of which, together with a selected embodiment well illustrating the principles involved, is described and illustrated in the accompanying specification and drawings.

Throughout the specification and drawings like reference characters are correspondingly applied, and in the drawings lintervening object,

F1g.I 1s an outer edge view of a tree insulator in accordance with my invention.

Fig. II is a -plan view, partly in section.

Fig. III is an inner edge view.

Fig. IV is an end view.

Fig. V indicates diagrammatically the deviection of a cable past a tree, post or other Massachusetts, lhas invented certhis objection, I

relative towhich the in-` Sulateddeector is effectively positioned by vthe tension .of the cable itself, and

F1g VI 1s a longitudinal sectional view vshowing a modifi l I cation. y tree insulator is of one-piece construction and 1s preferably made throughout of suitable insulatingmaterial. The insulator is offset between its ends as indicated at l lto deflect the current carrying cable C past an intervening tree or other obect T, and -at its ends 2 extends cable.

The outer face' of said offset portion l 1s provided with a continuous groove 3 which extends diagonally across the end portions. 2 of the insulator to the inner surface thereof' as indicated at 4 and. thence outwardly along the inner faces of said end portions as indicated at 5l to permit the cable AC to be inserted thereinto. The current carrying cable C is lodged within the groove 3 as shown in the several figures ofl the drawings, and is thus deflected pastthe tree'.'

By this construction I avoid the necessity of otherwise fastening the deilector to the tree T, the twist therefore, the cable-is not only suiciently offset to pass a tree or other intervening object, but both the tree and cable are protected fromv injury, and short circuits in the distributing system avoided, all in a construction wherein the cable itself is utilized to support the insulator.

As an alternative form which may be used under certain conditions of service, the insulator extends in a strai ht line from' end to end, (see Fig. VI) andg a cable-receiving groove similar to that shown in Figs. I' toV, inclusive, such groove extendin along the outer face of the insulator am? crossing adjacent'the ends thereof tothe inner face of the insulator and thence outwardly alongsaid inner face to the ends of the insulator.

In both forms, the cable itself solely supports the insulator relative to the tree, thus avoiding the use of special fastenings.

While I have discussed my invention as a tree insulator it. will be understood that such treatment is purelyillustrative and in no way limiting.

Various modifications in the construction in the line of the Y in the taut cable C imvparted by the offset groove 3 being relied is provided with 'Y Sio of my device may obviously beresorted to without departing from the spirit of my invention, it within the limits of the appending claims.

What I therefore claim and desire to -secure by Letters Patent is:

l. A cable deecton'consisting of a member grooved to receive a cable, the end porin proper cable-deflecting relation to the object around which the cable is to be deliected.

2. A deiiector comprising a member h aving a cable retaining guideway continuously from end to end thereof, the ends of said guidewa'y being disposed substantially in alinement with each other and on the -nner 'surface of said member and the intermediate. portion of said guideway being offset relative to said ends and extending along the outer surface of said member so as to deflect a portion of thecable lodged within said guideway out of the line of the cable and thereby anchor the cable and d'eector 3. A cable delector comprising a member having acable retaining guideway, the end portions of said guideway being dlsposed in the line of the cable, and said guideway between its ends being offset to deflect the cable'around an object disposed in the line of the cable and the deflection of the cable anchoring the cable against longitudinal movement in said vguideway, the lodgment of the cable in 'said guideway being relied upon solely to position .the deflector in proper cable deecting relation tothe object around which the cable is to be delected.

In testimony whereof in presence of two witnesses.
